The Code Book. When I wrote my first book, Fermat’s Last Theorem, I made a passing reference to the mathematics of cryptography. Although I did not know it at the time, this was the start of a major interest in the history and science of codes and code breaking, which has resulted in a 400-page book on the subject, an adaptation of the book THE SIMPSONS AND THEIR MATHEMATICAL SECRETS The Simpsons and their Mathematical Secrets.

WHAT IS MATHEMATICS REALLY?

According to Suetonius, Caesar simply replaced each letter in a message with the letter that is three places further down the alphabet. Cryptographers often think in terms of the plaintext alphabet as being the alphabet used to write the original message, and the ciphertext alphabet as being the letters that are substituted in place of the plain letters.

Cryptographers often think in terms of the plaintext alphabet as being the alphabet used to write the original message, and the ciphertext alphabet as being the letters that are substituted in place of the plain letters.

Cryptograms. Cryptograms are encrypted messages, and this page illustrates some cryptograms which you can try to crack. The cryptograms are divided into three categories, which increase in difficulty. These are: Each cryptogram section starts with a brief description of the cipher and hints as to how you can crack thecryptograms.

The book was first published in 1967, and at the time it was highly controversial because cryptography was such a secretivesubject

The Pigpen Cipher was used by Freemasons in the 18th Century to keep their records private. The cipher does not substitute one letter for another; rather it substitutes each letter for a symbol.SIMON SINGH
